SPECIFICATION forming part of Letters Patent No. 526,823, dated October 2, 1894.

i Application iiled March 14, 1894. Serial No. 503,549. (No model.)

To all whom it may concern:

Be it known that I, SINOLATR STUART, of Plainfield, in the county of Union and State of New Jersey, have invented a new and usefullmprovementin the Construction of Ships and other Vessels, of which the following is a specification.

This invention is in part applicable to allV Figure l represents a transverse section ofparts of one side and of the bottom of a vessel embodying my improvement. Fig. 2 represents a similar section on a larger scale than Fig. l, through the bilge and adjacent parts; Fig. 3, a section taken lengthwise of the vessel in the line ofgFig. 2; Fig. 4, a section taken lengthwise of the vessel about in the line y y of Fig. 2.

Similar letters of reference designate corresponding parts in all the iigures.

A designates one of the iioor channels constructed of channel iron or steel arranged to present its flanges in the direction of the length of the vessel. These channels are of such length that they terminate at the lower turn of the lbilge.

B is the tank extending all across the bottom of the vessel and having its top C at about the height of the upper turn of the bilge.

D is one of the side frames represented as of bulb angle iron. This frame instead of being continued to the iioor of the vessel as is common in iron and steel ships, terminates at the upperturn of the bilge and above the tank top C.

The interruption between the Hoor channel A and the side frame D is occupied by a Wide bracketplate E which is arranged within the tank B and conforms to the bilge of the vessel. The lower end of this bracket plate which extends to the bottom plates F of the vessel, is lapped over the face of the channel A and riveted thereto as shown at a a. The upper end of said bracket plate is connected by an angle-iron b and rivets c o with the margin strake e of the tank top C, the said margin straks extending to the side of the vessel at or near the upper turn of the bilge. The said bracket plate is represented as stiffened by an angle-iron d riveted along its inner edge and an angle-iron f riveted along its outer edge and conforming to the bilge. This bracket plate E Within the tank gives very great strength to the bilge of the vessel and affords greater facility for theconstrnction of a vessel with a water ballast tank.

Above the top of the water ballast tank is a bracket plate G which occupies the angle between the side of the vessel and the margin strake c of the water ballast tank top. This bracket plate laps against the side of the angie frame D and is riveted there by rivets g. The bottom of said bracket plate is riveted by rivets fi, to an angle-iron j which is also riveted to the margin strake e of the tank top by the same rivets which secure the angle iron b of the lower bracket plate E to the margin strake. The said angle-iron j is represented as further riveted by rivets 7c to the deck beam K which lies immediately above the Water ballast tank top. 'The inner edge of the said bracket plate G is stitfened by having riveted to it an angle-iron h. This bracket plate G combines with the bracket plate E to' form a practically continuous connection between the side frames and the floor channels.

In Fig. 1, I have represented the deck L as supported upon channel-iron beams M, of which, however, only one is visible in the drawings, the said channel-irons having their Webs arranged vertically and having their flanges presented in the direction of the length of the vessel. These beams which make a very strong support for the deck, are connected to the side frames by brackets N in substantially the same manner in which the angle and T-beams in common use are connected.

What I claim as my invention is- 1. In an iron or steel vessel having a Water ballast bottom tank, the combination with the Hoor channels and with the margin strakes in the top of the tank extending all the way to the sides of the vessel at or near the upper forming to the bilge arranged Within the tank4 turn of the bilge, of bracket plates arranged Within the tank conforming to the bilge and united with the said margin strakes close to the bilge and also united with the floor channels, substantially as herein set forth.

2. In an iron or steel vessel having a Water ballast bottom tank, the combination of floor channels terminating at the lower turn of the bilge, side frames terminating above the tank at the upper turn of the bilge, brackets conand connected with the ioor channels and with the margin of the tank top, and bracket plates above the tank top connecting the mar- 15 gin of said top with said side frames, substantially as herein set forth.

SINCLAIR STUART.
